How long should you cook Spaghetti Squash in the microwave?

Cutting Up Spaghetti Squash Before Cooking Advantages: It cooks faster. Disadvantages: Like any winter squash, hacking it up takes muscle and a sharp knife or cleaver. It's also a bit more work to scrape out the seeds and pulp when they are raw. Method: Just get in there and cut it in half (lengthwise) or quarters. You don't want to cut it up too small unless you want short strands. Scrape out the seeds and pulp as you would with any squash or pumpkin. Microwave 6 to 8 minutes (let stand for a few minutes afterwards) Separate strands by running a fork through in the "from stem to stern" direction.
